\section{Summary} \label{sec:summary}
In this \paper, we introduce the goals, design and implementation of NDNS,
which provides scalable, universal and authenticated storage service in NDN network.
Design wise, NDNS also inherited the basic concepts and design from DNS,
with adapting to NDN architecture.
We also present detailed comparison between NDNS and DNS together with its following enhancements.
NDNS makes use of finer granularity caching, which leads to different iterative query process;
Distributed way of update and multiple-master model of zone synchronization improve robustness and performance of the NDNS,
especially when there are more and more mobile devices.
What is more, security mechanisms for query, update and zone synchronization are simplified since every RR self-contains its authentication information.
